Title:
EJECTOR
Document Type and Number:
WIPO Patent Application WO/2014/076903
Kind Code:
A1
Abstract:
A mixing section (15e), which mixes an injection refrigerant and a suction refrigerant, is formed in the internal space of a heating-side body section (15b) of a heating-side ejector (15), across a range from a refrigerant injection port (15c) of a heating-side nozzle (15a) to an inlet (15h) of a heating-side diffuser (15g). In addition, the mixing section (15e) circulates the refrigerant, and is formed in a shape in which the area of the refrigerant passage gradually decreases toward the downstream side, and the area of the refrigerant passage of the inlet (15h) is set so as to be smaller than the area of the refrigerant passage of the refrigerant injection port (15c). According to this configuration, the flow rate of mixed refrigerant inside the mixing section (15e) is slowed to a value lower than the two-phase speed of sound (αh), suppressing the generation of shock waves inside the heating-side diffuser (15g), and stabilizing the boosting performance in the heating-side diffuser (15g).
